IMPRGVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 14%',51ydeted February 17, 1874; application filed December 20, 1873.-

To all whom it may concern:

Be it known that I, ZEBULON HUNT, of Hudson, NewYork, have invented certain Improvements in Cooking-Stoves, of which the following is a specification:

The object of my invention is to combine and arrange two f1re-pots with separate grates in a cooking-stove, so that they may be used separately or in combination by placing a dividing partition in the ash-pit, and providing each apartment with an independent cold-air draft, and continuing such separation up between the fire-pots to such height as to have two entirely distinct and separate fires, one alone in either pot, or one entire fire throughout by uniting the two above the fire-brick partition.

As intimated above, either of these iirepots may be used separate and alone, or both at once, yet each independently of the other, producing two separate fires, or both together7 so as to form one united and uniform ire. In warm weather, or when but little heat is required, one iire-pot only may be used.

This arrangement is the union of two stoves in one, eected principally by the partition A and the hre-brick partition B (see Fig. 2) between thc two lire-pots, yet the latter not so but that the two may be used jointly for the production of one combined fire.

Figure lA is a perspective view of this combination and arrangement. Fig. 2 is a longitudinal vertical section of the stove in the line ot' this partition. Fig. 3 is a plan vview ofthe bottom of the divided ash-pit.

The partition A commences on the bottom and divides the ash-pit into two equal parts, and each is provided with its own separate and independent cold-air drafts. It is extended up to the bottom of the rire-box, and from thence continued with fire-brick to the height of the lire-pots, but hollowed out in the middle, and otherwise so formed as, with the other brick and the iron front piece, to complete the circular form of the iire-pot on each side.

Fig. 2 represents the hollowin g form of this fire-brick partition B. This form is adopted for the purpose of uniting the coal and forming one entire fire the whole length of the rebox, to use less coal between the boilers where the least heat is required, and to confine the fire to. either one of the fire-pots when only one is wanted. These fire-pots are constructed of hre-brick, except the 'front plates a a', which constitute only about one-quarter of each, and are easily replaced when required.

The products of combustion, in leaving the iirebox, pass over the oven, and between it and the top plate of the.stove, in one broad flue, in the usual manner7 after which they pass down on one side of a dividing-partition in the back flue, make the circuit of the bottom, thence up on the other side of the back partition, and into the pipe. This is their course when the damper in the top flue of the stove is closed; but when open they pass directly into the smoke-pipe.'

The open circular reciprocating grates employed in the hre-pots are of great utility in maintaining a free draft and clean open re, and are believed to be a novelty in cooking stoves. So, also, two fire-pots of nre-brick, with cast-iron grated fronts a a', are `new fea tures in the construction of such stoves.

What I claim herein as my invention is- 1. The partition A in the ash-pit of a cook ing-stove, connected and combined with the partition B in the fire-box, substantially as and for the purpose herein set forth. Y

2. The combination of two fire-pots and grates, constructed as herein described, with and in relation to their respective independent ash-pits and cold-air drafts, substantially in the manner and for the purposes set forth.

zEBULoN HUNT.
